Pretty good math, it takes a heck of a 4 x 4 to get in the 150's let alone in the 160's. first glance always gets me close and he has a 140 inch frame. I agree on the 23 inch main beams using a 7 inch ruler like his ear. He probably does gross in the low 150's but will net in the high 140's. I have a buck on the wall I tool in Davis County a few years ago and it reminds of him especially his height. Age, I don't say much and give numbers there but it's fun ready everyone's thoughts. He has some growing left to do and like most bucks would be tough to pass.
